HOSE NOZZLE.

Application filed January 22, 1924. Serial No. 687,720.

T o all whom z't may concern.'

Be it know that I, THOMAS HALEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Hose Nozzles, of which the following is a speciiication.

This invention relates to a nozzle for lire hose including a tubular sectional body and an elongated gradually tapered double cone, fixed to the body and occupying the longitudinal center thereof. In Letters Patent of the United States No. 854,641, May 21, 1907, I have shown a hose nozzle of the character above indicated.

The present invention is embodied in certain improvements hereinafter described and claimed, in the means for securing the cone to the nozzle body.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is a side elevation of aV hose nozzle of the type to which my improvements relate.

Figure 2 is a longitudinal section of the nozzle, the cone being shown in side elevation, and the spider hereinafter described being shown partly in section.

Figure 3 shows the cone and the spider partly in section and partly in elevation.

Figure 4 is a perspective View of the spider.

The same reference characters indicate the same parts in all of the figures.

The tubular nozzle body comprises a base section 12, a middle section 14, having a screw thread connection at 15 with the base section, and an outer section 16, having a screw thread connection at 17 with the middle section.

20 designates the outer section, and 22 the inner section of a double cone which eX- tends from within the base section, through the middle section and into the outer section, said cone sections having a screwthread connection at 21.

The form of the cone, the relative arrangement of the cone and the nozzle body, and the construction, arrangement and function of the parts shown by the drawings, and not described hereinafter, are the same as in my former patent, above mentioned.

In carrying out theV present invention, I

connect the cone with the nozzle body by a spider, which is formed as an independent part, is detachably secured both to the cone and to the body, and is clamped between the sections 12 and 14 of the body, and the sections 2O and 22 of the cone.

The spider is composed of an outer ring 24, an inner ring 25 concentric with the outer ring, and arms 26 connecting said rings, segmental water ways being formed by the ring and arms, as shown by Figure 4. The cone sections 2O and 22 are provided with annular opposed clamping faces 27 and 28, which are caused, by the operation of screwing one section into the other, to bear with a clamping pressure on opposite edges of the inner ring 25, and thus firmly and detachably secure the spider to the cone, as indicated by Figure 3.

The nozzle body sections 12 and 14 are provided with annular opposed clamping faces 29 and 30, which are caused, by the operation of screwing one section into the other, to bear with a clamping pressure on opposite edges of the outer ring 24, and thus firmly and detachably secure the spider andI the cone to the nozzle body, the spider having been previously secured to the cone, as above described.

The spider, separably secured to the cone by the operation of screwing the cone sections together, and to the nozzle body by the operation of screwing the base and middle nozzle sections thereof together, is a very desirable substitute for the radial arms or wings inseparably united to and radiating from the cone section 22, and engaged at their outer ends with an internal screw thread in the base section 12, as shown by my former patent. The arms or wings of said patent are necessarily separately formed and solderedor brazed to the cone section, so that much more time and labor were required in providing the cone with means for attachment to the nozzle body than are required by my improved construction.

The spider may be cast, or otherwise formed, in a single piece and is secured as a unit to the cone by the operation of assembling the sections of the latter, after which the cone is secured to the nozzle body by the operation of screwing together two of the sections' of the body, this operations, also provided with opposed annular I0 tion locating the cone in the exact posit-ion clamping shoulders, rand a spider composed desired relative to the body. of an inner ring clamped between the I claim: f shoulders of the cone sections, an outer ring A hose nozzle comprising a .tubular body clamped between the shoulders of the body composed of separably connected sections, sections, and arms connecting said ring. 15 two of which are provided with opposed In testimony whereof I have aixed my annular clamping shoulders, a double cone signature. composed of two separably connected sec- THOMAS HALEY.
